BUNDLE-TYING DEVICE.

Specification of Letters Patent. I llgttentd Mimi', 21, 1916,

Aipplcation filed September 29, 1914. Serial No. 864,119.

M v invention relates to' improvements in bundle tying machines for tying wire around bundles of lumber or. other articles.

The objects of my improvement are, 1irst, to provide a `wire receiving'and twisting head; second, to afford facility forV impart- .ing rotary. movement thereto; third, toprovide means to impart longitudinal movement to the twisting head during rotary movement thereof; fourth, to provide means for drawing the wire taut before twisting the same, and fifth,'to provide means to normally hold a wire tightening and twisting means at an inclined position prior to operation thereof. f

I attain the above .objectsby the devices illustrated in theA accompanying drawings described and claimedand the equivalents thereof. l

Referring to the drawings wherein like characters of reference denote similar parts throughout the several views: Figure 1 is a side elevation, with portions broken away, of my improved-bundle tying device; Fig.

,2- is a detail taken on line 1-#1 of Fig. 1. Fig.'3 is a detailtaken on line 2-2 of Fig. 1. Fig. 4 is a plan view of the device Fig 5 is a longitudinal section of the wire-'twisting head. 4

. As is clearly shown in the drawings, the embodiment of the device which I have se.-

lected for the purpose of illustration con sists in a base 1 suitably secured toa table or other object.

2 is an offset arm, preferably integral with the base 1. 3 designates a lhinge-pin for pivotally connecting a hinged member-4 to the'base 1.-

Hinged member 4 is provided with a eutaway portion 5, the sides of whichare provided with the'ways 6 adapted to slidably 4receive the wire-tightening block` 7. This y ing 14.`

block is provided with a wire-gripping device 8 of any suitable construction.

9l designates an operating lever pivoted at its -lowe'r end to the ears 10, which ears dependfrom the hinged member 4. Lever 9 is preferablv fork-shaped at its vlower end and is provided with a pair of opposed slots 11 adapted to receivea pin 12 projecting yfrom each side vface of the reduced rear end 7' of the wire tightening block 7.

' 13 and 14 designate suitable bearings carried by hinged member 4 and adapted to support a suitable wire receiving and twisting. member. The wire receiving and twisting member consists of a spindle 15, pinionY 1G fixed -to the spindle, 'the spindle formed with a threaded portion 17, and a ltwisting head 18. The twisting'member is provided with 'a longitudinal eccentrically located wire-receiving opening 19 and an inclined wire-receiving hole 20, the front end of which'is also eccentrically located with reference to the face of the head 18. This latter opening 20 extends only partly` through the twisting-head 18. The spindle 15 is mounted in the bear-ing 13 and the screwthreaded portion 17 is threaded in the bear- The means for rotating the wire-twisting member consists of a segment-gear 21 adapted, tol mesh with pinion 16. The segment-gear is pivotally mounted upon a pin p 22 extending from the bracket 23 carried by f the hinged member`4. 1 Segment-gear 21 is provided with a suitable operating lever or handle 24.

25 designates a suitable compression spring mounted on arm'2 and engaging at its upper end the hinged'member 4 tofnormally cause the hinge-member' to assume an inclined position, as shown in dotted lines in Fig. 1.Y

The angularend of the hinged member 4 i ,formed by means of a horizontally extending member 26 and a downwardly extending bracket 27 forms xa corner to receive the articles to be tied. Member 27 is provided witha hook 28. -A .foot pedal 29 is suspended from the hook 28. The operator may by putting his foot on the pedal. pull vthe hinged member` into alinement with the base 1,I thereby bringing the bundle-receiving corner into contact with the goods to bei tied, prior to twistingthe wire which is pulled around the goods by the operator.

30 designates a pin secured to the hingedmember 4 spanning the opening 5 to act as a guide for the wire.

The operation of the device is as follows: Th'ewire is first pulled through the opening 8 of the sliding wire-tightening block 7,

then through the longitudinal wire-receiving opening 19- ofthe twisting member, suiicient wire being pulled through to pass around the bundle to be tied. The hinged member is then lowered to bring the bundlein Fig. 1 to lock the wire.

receiving corner into contact with the goods.

lThe wire is then pulled around the goods and passed through the inclined hole 20 of the twisting-head 18 and bent back as shown The lever 9 is then pulled back, taking the slack out of the wire and drawing it taut around the goods. Lever 24 is then turned through half of a revolution in the direction of the arrow,

thereby rotating the head 18 and twisting the wires adjacent the end of the head 18.

During the rotary movement of the head` and the twisting of the wire, the head 18 is caused by its screw-threaded portion 17 to move longitudinally, thereby withdrawing itself from the bundle as the wire is twisted. The wire is then'cut by any suitable means. After the wire has been severed, the lever 24 is moved back to its original position, bringing the head 18 back toits initial position ready for another operation. A

Having thus described my invention, what I claim and desire to secure by Letters Patent is: u

1. In a bundle tying machine, a hinged member, a wire tightening means, means for actuating said wire tightening means, a wire twisting member having a pair of eccentrically located wire receiving openings, said member having a threaded spindle en-v gaging said hinged member, and means'for rotating and simultaneously retracting said wire twisting member.

2. In a bundle tying machine, a hinged member, a slidably mounted wire tightening block arranged on lsaid hinged member, a lever adapted to actuate said block, a wire 'twisting head mounted on said hinged memtighteningvblock arranged on said hinged' member, a lever adapted to `actuateA said block, awire-twistingvhead mounted on said hlnged membenl means for .rotating said wlre-twisting head in either direction, and

means for imparting longitudinal movenient tothe .wire-twisting head simultaneously with the rotary movement imparted thereto.

4. In a bundle tying machine, the combination with a base having'an oifset arm, a hingedmember connected' to said base, a wire-'tightening block slidably mounted on said hinged member, and an operating lever for moving said wire-tightening block; of a wire-twisting head having. an eccentrically located longitudinal Wire-receiving -opening and an eccentrically located inclined wirereceiving hole, a slidable spindle integral with the wire-twisting head, a pinion fixed to` said spindle, an internally threaded bearing fixed to the hinged member, a screw-thread formed on said spindle adapted to be received in said internally threaded bearing, a segment-gear pivotally mounted upon the hinged member adapted to mesh with said, pinion, anoperating lever extending therefrom, a foot pedal depending from the hinged member, andv a compression spring interposed between the oii'set arm vand said hinged member, for the purpose set forth.

5. The combination with a base, a hinged member connected thereto, means to normally cause the hinged member to assume an inclined position, a wire-tightening block slidably mounted on said hinged member, a leverl for operating said wire-tightening receiving corner formed atthe freeend of said hinged member, and means for bringing said hinged member to a horizontal position and retaining` it in such position during the tying operation, substantially as set forth.

In testimonywhereof, I affix my signature in presence of two witnesses.
